[jira] [Commented] (ACCUMULO-1972) Range constructors call overridable method

Christopher Tubbs commented on ACCUMULO-1972:
-

Thanks for the patch, [~coffeethulhu].

I have some concerns about the patch.

Doing nothing means it is possible for careful developers to override the 
method. Applying this fix prevents users from doing the thing they needed to do 
that would have caused the bug in the first place (that is, override the 
method). I don't think this is the best fix we can do, as it breaks the API and 
prevents the only use case that would have been affected by the bug.

It seems to me that a better fix might be to move the implementation to a 
private method, which can be safely called in the constructor, and also be 
called in the public method. That way, if the user overrides the public method, 
the behavior of the constructor will be unaffected. This fix would also allows 
us to avoid an API breakage, which means we can fix it in 1.7.x and 1.8.x, 
instead of waiting for 2.x.

> Several {{Range}} constructors call {{Range.beforeStartKey()}}, which is not 
> final. This is dangerous:
> bq. The superclass constructor runs before the subclass constructor, so the 
> overriding method in the subclass will get invoked before the subclass 
> constructor has run. If the overriding method depends on any initialization 
> performed by the subclass constructor, the method will not behave as 
> expected.  ??Item 17, Effective Java Vol. 2, Bloch??
> If {{beforeStartKey()}} cannot be made final, the code should be refactored 
> to make the constructors safe.

 Review comment:
   It would be nice to reduce the redundant code. One possible way to do this 
is to create an internal class like the following.
   
   ```java
 private static class LengthStats {
 private long min = Long.MAX_VALUE;
   ?  private long max = Long.MIN_VALUE;
   ?  private long sum = 0;
   ?  private long[] counts = new long[32];
   
 private void accept(int lenght) {
int idx;
   ? 
   ? if (length < minKey) {
   ?   min = length;
   ? }
   ? 
   ? if (length > max) {
   ?   maxKey = length;
   ? }
   ? 
   ? sum += length;
   ? 
   ? if (length == 0) {
   ?   idx = 0;
   ? } else {
   ?   idx = IntMath.log2(length, RoundingMode.HALF_UP);
   ? }
   ? 
   ? counts[idx]++;
 }
   
   void summarize(String prefix, SummaryConsumer sc) {
 sc.accept(prefix+"min", (min != Long.MAX_VALUE ? min:0));
   ?  sc.accept(prexif+"max", (max != Long.MIN_VALUE ? max:0));
   ?  sc.accept(prefix+"sum", sum);
   ? 
   ?  for (int i = 0;i < counts.length;i++) {
   ? if(counts[i] > 0) {
   ?sc.accept(prefix+".logHist."+i, counts[i]);
   ?  }
   ?   }
   }
 }
   ```
   
   Then create an instance of this class for each field and use it in the 
Collectors `accept` and `summarize` methods.

[jira] [Updated] (ACCUMULO-4730) Create an Entry length summarizer

>  that computes summary information about field lengths.  Specifically key

> incrementally.  For example can incrementally compute min, max, count, sum, 
> and log2 histogram.  I think these would be good stats to start with.  Count 
> and sum can be used to compute the average.  There is an example of computing 
> a log2 histogram in the Summarizer javadoc.
> The Summarizer could be named EntryLenghtSummarizer and possibly produce

> family.max=XXX
> family.sum=XXX
> family.logHist.6=XXX
> family.logHist.7=XXX
> etc...
> {noformat}
> This new summarizer would be placed in the 
> [summarizers|https://github.com/apache/accumulo/tree/master/core/src/main/java/org/apache/accumulo/core/client/summary/summarizers]

   @jmark99, I was going to merge `get_involved` and `mailing_list` into a 
[contactus](https://github.com/mikewalch/accumulo-website/blob/640b260ae411ef86b136864e3a8284d4bcce0fcd/pages/contact-us.md)
 page.  Btw, I am just copying what is being done on the [Fluo 
website](https://fluo.apache.org) which seems to be working as Fluo is getting 
more first-time contributors than Accumulo.  I think this is due to simple 
instructions. We could limit the pages to `contactus` , `how-to-contribute` and 
`contributor-guide`.  Things that aren't necessary for  the minimal `contactus` 
& `how-to-contribute` like lazy consensus, voting, etc could go into the 
`contributor-guide` page.

   @mikewalch , do you envision us keeping the 'get_involved' page in the drop 
down?. Since you address some ideas for getting involved I'm not sure it needs 
to be a separate drop down selections. It contains some information that 
probably isn't needed for someone just looking to get involved,i.e., lazy 
consensus info, voting, etc.  Any information on that page that is not already 
in the contributor guide could be added and the get_involved could be replaced 
with your "how to contribute" page.

   @jmark99, I like your idea.  We could add  the following text to the top and 
bottom of my page and link to your page. 
   
   ```
   This page provides basic instructions for contributing to Accumulo.  If you 
are looking for more information, check out the more comprehensive [contributor 
guide](/contributor-guide/).
   ```
   
   Contributors could start with the `how-to-contribute.md` page that I created 
(which could probably even be shortened some more) and then reference your 
guide if they need more information.

jmark99 commented on issue #37: Accumulo 4714 Create landing page for new 
developers
URL: https://github.com/apache/accumulo-website/pull/37#issuecomment-342826688
 
 
   @mikewalch, That was a concern as I was working on it.  It slowly kept 
growing as the various bits of information were being collected. I actually 
like the work you have done quite a lot. As a new contributor I think one is 
most interested in getting the basic info needed to get them started. Your page 
does a great job of that. The hope with the submitted layout was that a user 
could click on the topic that they were interested in and not bother with the 
additional information but in the end the page did appear to be a little 
overwhelming. (Information on git workflow, etc, would not be that relevant to 
a new user initially). I would be good with using your page as the basis for 
what a new contributor would need to do to get up and running and then find the 
appropriate way to link to the additional information.  Perhaps something like 
having the site point to your page as the one new developers would reference 
for initial contribution guidance and then use the page I created to  serve as 
an all-inclusive contributor manual or something like that (renaming it from 
index.md of course). That way we could add details as needed to the manual 
since the role of the page would be to serve as a comprehensive repository of 
contributor-related  information.  Thoughts?
